Find the coordinates of the centroid of triangle RST. SHOW YOUR WORK so I can see if the answer makes sense (no links)

zimovet [89]

Note the coordinates of each point: R(-4, 5), S(5, 1), T(2, -3).

The centroid is the point whose coordinates are the average of the coordinates of R, S, and T.

x-coordinate: (-4 + 5 + 2)/3 = 3/3 = 1

y-coordinate: (5 + 1 - 3)/3 = 3/3 = 1

So the centroid is (1, 1).

A customer went to a garden shop and bought some potting soil for $12.50 and 5 shrubs. The total bill was $62.50. Write and solv

lesya692 [45]

Answer: Equation: $5x = 62.50 - 12.50$ or $x = \frac{62.50-12.50}{5}$

x is the cost of each shrub x = $10

Step-by-step explanation: Total bill = $62.50.

Subtract the cost of potting soil for $12.50 to find the cost of just the shrubs. 5x equals that amount

5x = 62.50 - 12.50

5x = 50 divide both sides by 5

5x/5 = 50/5

x = 10

What is 85 divided by 5 in distributive property

Lilit [14]

Answer:

Step-by-step explanation:

85 divided by 5 in distributive property

85 can be break into 80 and 5

80+5 is 85

Now we divide each term by 5

$\frac{85}{5} =\frac{80+5}{5} =\frac{80}{5} +\frac{5}{5}$

Denominator 5 is distributed 5 inside the numerator

$\frac{85}{5} =\frac{80}{5}+\frac{5}{5}=16+1=17$

17 is the final answer
